thought or movement, was SHOWN Ny
rise or fall in the liquid in the narrow
neck of the vessel. With large balance
on which the horizontal human body may
be poised, he has found that ones
thoughts may be literally weighed, and
that even dreams or the effect Of slight
sound during slumber, turns the blood to
the brain sufficiently to cause tie balance
to fall at the head. When the brain OF
the person balanced is being relaxed from
thought the flow is toward the feet, with
a corresponding oscillation. The investl-
gator has continued his studies of the cir
culation until it seems that he may almost
read ones thoughts and sensations. A
single pulse-beat shows him whether
person is fasting or not; two beats serve
to determine whether the subject is a
thinking or needless one, whether asleep
or awake, cold or warm, agitated or calm
The changing pulse even told him when
a professional friend was reading Italian
and when Greek, the greater effort for the
latter having due effect on the bloodHow.
The possibility of changing one metal
into another seems to be still an open
question, and chemistry may yet accom-
~
plish the oft-ridiculed purpose OF the
old alohemists. A spectroscopic study OF
the sun has given Prof. j, N. Lockyer,
the English astronomer, reason for be-
lieving that the substances now regarded
as elementary are really compound; while
Prof. VIM. Crookes, probably as able a
physicist as any living, finds that the OBJ
serve phenomena of chemistry and physics
point very strongly to the conclusion that
all the so-called elements are but varla-
tions of single form of matter, which be
terms "protyle." Prof Crookes agrees
with Faraday that "to decompoSe the
metals, then to reform them, to change
them from one to another, and to realize
the once absurd notion of transmutatlon,
are the problems now given to the chemist
for solution
1t appears that communication by tele-
phone to great distances, though an IN
teresting and wonderful scientific achieve
ment, is not likely to prove commercially
important. Estimates by DR.. Weitlisbach
place the cost of a telephone line l20O
miles long, over which speech is possible
at over $3.50, 1000; and to make such line
profitable it must earn a dollar minute,
q brief conversation thus costing So or
$40. The telegraph works at this dis
tance at about tenth of the cost, and IS
cheaper for all distances of more than 3Oo
miles, the economy being with the teie'
phone below about that limit
Denmark, as is we'll known, is remark
ably low country. 1t has long been sup
posed that it's highest land was a hill Oh
feet above sea-level; but the surveys OF the
past season show that there are two high
er points in the kingdom m-oDe reaching an
elevation of $50 feet, and the other $40
feet.
The adylsablility of testing as foggy
weather signals sudden fashcs-such as
those of gunpowder-h has been suggested
to the British lighthouse authorities by
Lord Rayleigh and Prof. Stokes, who
think the flashes might attract attention
where an equal fixed light might escape
notice.
The beaver is reported by Prof, Collett,
the Norwegian zoologist, to have become
extinct in northern Norway, about lou |
only being still alive in the south.
Among the many curious and interesting |
works of the largest library in the world,
at Paris, is Chinese chart of the heavens,
made about 600 B. G. In this chart 1850 |
stars are correctly inserted, as corrob. |
GRATED by the observations of modern
astronomers.
An interesting method of recomposing
white light from the colors Of the spec
trum has been described to the Paris
Academy of Science by NOES. Stroumbo,
A prism is mounted upon an axis parai'
lei to its edges, ard so placed that the
seven prismatc rays are thrown on
white screen. The prism is then revolved,
and when its rotation has become suth-
GENTLY rapid the colors disappear, and
band of white light results
The teeth of an individual often vary
greatly in hardness at intervals, and
Berlin physician, DR.. W, D. Miller. is ez-
perimenting to show that this is due to a
varying proportion of lime salts in the
food.
